Storing it upright reduces the beer’s surface area that’s exposed to air, which helps slow down the oxidation process that can cause the beer to go stale or develop off-flavors. Additionally, storing it upright can help to prevent contamination from the cap or cork, which can sometimes harbor bacteria that can spoil the beer.
When beer is stored on its side, it can result in a line of yeast sediment, referred to as yeast ring, sticking to the bottle, which isn’t only an eyesore but can also lead to an unpleasant taste.
While it may be tempting to store beer on its side for convenience, storing beer upright is recommended to ensure it stays fresh.
Aging beer can enhance flavor and complexity, as certain types of beer may continue to develop and evolve, just like wine. This process is known as aging or cellaring. As beer ages, the flavors and aromas can change and mature, often becoming smoother, more relaxing and more complex.
For example, high-alcohol beers like barleywines, imperial stouts and Belgian quadrupels can benefit from aging. The harsh alcohol flavors in these styles can mellow out and become more integrated with the other flavors over time.
However, not all beers are suitable for aging, and the aging process can be unpredictable. Some beers may lose flavor or oxidize over time, resulting in off-flavors and aromas. They should, therefore, not be stored for long.
Researching and understanding specific beer styles and their aging potential is important before storing them for aging.
Proper beer storage is crucial for maintaining its quality and flavor. By following the above guidelines, you can ensure that your beer stays fresh, delicious and ready to enjoy whenever the occasion arises.
